*'''Start''': Select the earliest date and time (in UT) that the observation may start. These can be selected from a calendar, so you don't need to worry about the format.
*'''End''': Enter the end date and time (in UT) for the observation window. For an observation with no specific time constraints, the window could be as wide as the full season that the target is visible, to allow the greatest chance of it being observed. For a time-critical observation, the window should only cover the duration of the event, plus overheads. Once you have added a feasible end time, a visibility plot will appear.
Clicking on the green icon at the top of the window section will create additional windows for you to specify, which gives the scheduler discrete options as to when to make the observation.

*'''Cadence''': The options are:
